Moving already Installed OpenFOAM to different machine (user)

Hi Everyone,
How to make sure that moving an already existing OpenFOAM installation (built from source) to a different user in same machine or a user in different machine alltogether (assuming all OS, package installation to be the same), works fine (so that one needs not build it again, because its time-consuming). I mean, just resetting the environment variables would be enough to complete the installation for a new user/machine ? My actual problem, is that I am trying to run OpenFOAM on a grid. And I am using my local installation for the grid-user (making sure the permission compatibility) . And I am not able to run OpenFOAM on grid as grid-user (after resetting the env variable according to grid-user) Following error occurs on running a simple blockMesh Command: word::stripInvalid() called for word CN=5a631e00-2cdb-4b59-861f-4580f7e05fe2 For debug level (= 2) > 1 this is considered fatal /tmp/openfoam-test/runOpenFoam: line 23: 16241 Aborted blockMesh "CN=5a631e00-2cdb-4b59-861f-4580f7e05fe2" is actually the grid-userId on the Grid. |

Greetings Lokendra and welcome to the forum!
I'm sorry for starting off with a rant, but I'm going to have to say this first: XtreemOS is stupid It's breaking a rule in user naming: No stupid characters in the user names, which should also be short by definition! So, AFAIK, the explanation is this: OpenFOAM at the core needs to know some $HOME and user details, so it can more easily know where to tread in a multi-core environment. And the user name is also checked for "illegal" characters, to avoid some bad things to happen further down the road with the file systems. So, I'm going to try to post some minor changes (or hacking ) you need to do to OpenFOAM's file "src/OSspecific/POSIX/POSIX.C". Do this on your original machine/build environment! So, open that file and next I'll give the changes to be done. ... But first, some introduction to the addition needed on your grid account - a new variable in the shell environment is crucial to be defined in .bashrc or something like that: Code:
export MYUSER="ofuser" And make sure your HOME variable is defined: Code:
echo $HOME Now, as for the changes in the OpenFOAM's file POSIX.C:
OK, now run ./Allwmake as you've done before. It should build quite quickly, since it will only update libOpenFOAM.so Keep us posted on the outcome! Best regards, Bruno

Does anyone know how to solve this problem in Windows?
I try to run OpenFOAM in Windows. The same error appears when I try to run OF. I cannot find the files you mentioned in my WIndows version, thus I don't know how to solve this problem. Maybe someone knows more. Thanks a lot. Best Regards, tH3f0rC3 |

Hi,
it is the nearly the same error: word::stripInvalid() called for word *** For debug level (= 2) > 1 this is considered fatal *** is another word. It is my full name. Maybe because I named the computer like that, I don't know. When I switch off all debug options in the controldict file OF runs. I haven't found out if OF really runs without a mistake. This error message occurs no matter which command I have typed in (laplacianFoam, chtMultiRegionFoam, blockMesh...) Best Regards |

Hi tH3f0rC3,
Ah, that makes it a lot clearer The solution for that and some other issues are described at openfoamwiki.net, on this section: Setting up shop in Windows I didn't even remember that I briefly wrote some tips on how to use MSys there! A year flies by in an instant... (check the history link at the top of the page) and parts of my memory goes with it... Good luck! Bruno

I Don't know exactly what have done, but OF works now.
I think the paths have not been set correct and now they are. New problem: I want to have a look at the simulated results with paraView. I have paraView installed but in WIndows paraView needs VTK files, as far as I know. Thus I have tried to foamToVTK the calculated files. The VTK files are created but paraView can't read. The following error message appears in paraView when opening the vtk-files: ERROR: In ..\..\..\..\source\VTK\IO\vtkUnstructuredGridReade r.cxx, line 349 vtkUnstructuredGridReader (10C74FD8): Unrecognized keyword: u Another error message appears when starting foamToVTK : From function IOstream::compressionEnum(const word&) in file db/IOstreams/IOstreams/IOstreams.C at line 75 bad compression specifier 'off', using 'uncompressed' And then the foamToVTK starts. Do you think this causes the error in paraView? I don't think so, but I can't think off another mistake why paraView can't read the vtk files. Best Regards |

Hi tH3f0rC3,
Wasn't there a "parafoam.bat" file in the patch files!? Read step #4 of the previous link If you use a version of ParaView 3.8.0 or newer, you can open files of type ".foam, which what "parafoam.bat" does. If you still want to use VTK files, try: Code:
foamToVTK -help Bruno

There was such a file.
I use paraview 3.10.1 -> But how can I open the "normal" results of my solver without foamToVTK these results? I have copied the parafoam.bat to the bin directory of OpenFoam. Now I think I have to move the still installed paraView to another directory that the parafoam.bat can find the paraview.exe This step doesn't work, because I haven't the same directory files described in the link you've posted. I have tried to modify the parafoam.bat from echo.>case.foam start paraview.exe --data="case.foam" to echo.>case.foam start D:\programs\paraview3.10.1\bin\paraview.exe --data="case.foam" BUt this doesn't work. -> Or how can I create the .foam file myself? |

An extract from the link you posted:
Paraview should be installed in, or copied to, one of the following folders, according to the versions installed (these are only some of the possible versions): ThirdParty-1.7.0\platforms\linuxmingw32\paraview-3.8.0 ThirdParty-1.7.0\platforms\linuxmingw-w32\paraview-3.8.0 ThirdParty-1.7.0\platforms\linuxmingw-w64\paraview-3.8.0 This is exactly the thing I havn't done up to now, because I don't have such directories. And I can't find out where the parafoam.bat searches for the paraview.exe The source code of parafoam.bat: echo.>case.foam start paraview.exe --data="case.foam" Best Regards |

Hi tH3f0rC3,

Code:
echo.>case.foam It doesn't matter what the file contains, because ParaView only uses the file as a marker of the case to be opened. Best regards, Bruno

Would like to do similar thing in the openfoam grid.
I am leanring Openfoam and would like to install it on centos7. But the Openfoam officially just provide the docker version for centos7. So I compiled Openfoam from source on VM called "VM1" and it took several hours to finish. We have 4 VMs and I found if we tar the Openfoam folder on VM1 and scp it to other VMs, with preinstalled some libraries, we could run motorbike example successfully. So would like to confirm with you about two questions: 1. how to check if one Openfoam installation is correct or not. I previous use "foamInstallationTest" to check the Openfoam installation but it seemed it seldom failed at checking. So not sure if it is correct way to check if Openfoam installation is correct or not. 2. Can we use this kind of installation way such like "tar one pre-installed openfoam folder and untar it on another vm" to install openfoam? Thanks a lot for the reply! |

Quick answers @lhsihan:

As long as the system dependencies are also installed on the other machines, then it should work. That's essentially how Docker works...
